| 14 | .SH DESCRIPTION |
||
| 15 | This manual page documents briefly the |
||
| 16 | .B nettle\-hash |
||
| 17 | command. |
||
| 18 | This manual page was written for the Debian GNU/Linux distribution |
||
| 19 | because the original program does not have a manual page. |
||
| 20 | Instead, it has documentation in the GNU Info format; see below. |
||
| 21 | .PP |
||
| 22 | .\" TeX users may be more comfortable with the \fB<whatever>\fP and |
||
| 23 | .\" \fI<whatever>\fP escape sequences to invode bold face and italics, |
||
| 24 | .\" respectively. |
||
| 25 | \fBnettle\-hash\fP is a program that computes various message digests. |
||
| 26 | The output is different from the familiar md5sum and sha*sum |
||
| 27 | family. For each file, the file name and a colon is printed first, |
||
| 28 | unless input is read from standard input, in which case nothing is |
||
| 29 | printed. Then the hash is printed in chunks of 64 bits (16 hexadecimal |
||
| 79 | magnus | 30 | digits) followed by the name of the algorithm. In raw (binary) mode, |
| 76 | magnus | 31 | the hash is not split in chunks and is not followed by a newline. |
| 32 | |||
| 33 | .SH OPTIONS |
||
| 34 | This program follows the usual GNU command line syntax, with long |
||
| 35 | options starting with two dashes (`-'). A summary of options is |
||
| 36 | included below. For a complete description, see the Info files. |
||
| 37 | .TP |
||
| 38 | .B \-a, \-\-algorithm=\fIalgorithm\fP |

||
| 40 | .TP |
||
| 41 | .B \-l, \-\-length=\fIlength\fP |
||
| 42 | Truncate digests at \fIlength\fP octets. It is an error to specify a |
||
| 43 | \fIlength\fP greater than the normal length of the selected digest. |
